Question

Nandini cycle at speed of 10 km per hour for the first 30 minutes she then increased speed 220 km per hour for the next 3/2 before reducing her speed to 8 km per hour for the next 15 minutes find the total distance travelled by her while cycling.​

Answer 1

Answer:

Distance travelled in the first two hours is 10 * 2 = 20 km.

Distance travelled in the next three hours is 15 *3 = 45 km.

Total distance travelled = 20+45 =65 km.

Total time taken = 2 + 3 = 5 hours.

Average speed = 65 km / 5 hr = 13 km/h.
