Question

a man takes 2.5 hour to cover a certain distance at a speed of 5 km/h by bicycle .how long it will take to cover the same distance by bike at a speed of 40 km / hours.​

Answer 1

Answer:

0.3125 hours or 18 minutes 45 seconds

Step-by-step explanation:

Let's say the total distance traveled is s

s = v * t

s = 5 * 2.5

s = 12.5 km

If he travels at 40 km/h

t = s/v

t = 12.5/40

t = 0.3125 hrs

or 18 minutes 45 seconds
