Two places P and Q both on the parallel of latitude 26°N differ in longitude by 40°. Find the distance between them along their parallel of latitude.

 A ship sails from Pemba (4.5^°S, 39.5^°E) to Dar es salaam (7.5^°S, 39.5^°E). If it leaves Pemba at 11:30 am and arrived in Dar es salaam at 13:30 pm, use and R_E=6370km to find speed of ship in km/h 

Calculate the distance from Chagwe (5°S, 39°E) to Minga (12°S, 39°E) in kilometres. Use pi = 3.14, the radius of the earth R = 6370km and write the answer correct to 1 decimal place.

(b) If a bus leaves Chagwe at 8:00 am on Monday and travels at 40 km/hour, at what time will it reach Minga?

The two towns P and Q lie on the earth's surface such that P(65⁰N, 96⁰E) and Q(65⁰N, 84⁰W). Find the distance between the towns in kilometers and nautical miles.

A ship sails from point A(10⁰ S, 30⁰ W) to point B(11⁰ N, 30⁰ W) at a speed of 900 km/h. If it leaves point A at 10:00 am, when will it arrive at B? (Radius of the Earth (R) = 6400 km).

(a)An aero plane fires from Tabora (5°S, 33°E) to Tanga (5°S, 39°E) at 332 km/her. Along parallel latitudes. If it leaves Tabora at 3 p.m., find the time of arrival at Tanga air-port

(b)Another plane flying at 595 km/hr leaves Dsm (7°S,39°E) at 8:00a.m it Addis Ababa (9°N, 39°E) (parallel longitude)

(Radius of the earth R 6370km)

Two places P and Q both on the parallel of latitude N differ in longitudes

by  find the distance between them along their parallel of latitude.

A ship sails from point A (40⁰S, 30⁰W) due west along the same latitude to point B for 1000km. Find the latitude and longitude of point B. Use R=6370km and π = 3.14(give your answer in nearest degree).

Kicheko and Mtakuja are two villages on latitude 60°S. The distance between Kicheko and Mtakuja measured along the parallel of latitude is 1111km. Find the difference between their longitudes in two significant figures.

Calculate the circumference of a small circle, in kilometres, along the parallel of latitude 30°N (Leave your answer in surd form).

Find the distance (in km) between towns P(12.4°S, 30.5°E) and Q(12.4°S, 39.8°E) along a line of latitude, correctly to 4 decimal places.

Two towns, A and B, are located at (10⁰S, 38⁰E)  and  (10⁰S, 43⁰ E) respectively.

(i)Find the distance between the two towns in kilometers. (Use radius of the Earth, R = 6400 km and         .Give the answer to the nearest whole number.

(ii)Suppose a ship is sailing at 50 km/h from town A to town B. Using the answer obtained in part (a) (i), find how long will the ship take to reach town B.
