Question

A train covers 840 km in 14 hours . Find its speed in metre per second a. 6 1/3 b. 2 1/3 c. 15 1/3 d. 16 2/3​

Answer 1

Step-by-step explanation:

we know that speed =distance/time ...here time is in hours but we need it in seconds

speed=distance

time

speed=840km

time=14 hours..it is 14 x 60 x 60 in seconds

14 hours=50,400 seconds

840km=840,000 m

therefore speed =840,000

50,400.

hence answer is 0.06

Answer 2

Answer:

• Given:distance=840km
• time =14 hours
• speed =distance÷time
• 840÷14
• 60km\hr
• 60÷5\18
• so, speed is 16 2\3.
