A boy was riding a bicycle and was moving with speed of 12 km/ hr for 2 hours and with speed of 15 km/hr for the next 3hours. Find the total distance covered by him and his average speed
Answers
Explanation:
To find the average speed, we'll use the formula, Total distance ÷ Total Time. Let us solve—
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.
Hope you got the answer. Thanks a lot…
Answer:
case 1
speed = 12 km/h
time = 2 hours
distance = s ×t
=2×12
= 24 km
case 2
speed = 15km/h
time= 3 hours
distance = s×t
15×3
= 45km
total distance = 24km+ 45km
= 69 km
average speed = total distance/ total time
=69/5
= 13.80km/h
