Question

Running at constant speed, Leo can cover a distance of 1 km in 34/5 of a minute. How far can he run at the same speed if he runs for an hour without stopping?

Answer 1

1 km in 34/5 of a minute
means
1 km in 34/5÷60hours
so in 1 hour =60×5/34 = 8.8 km

Answer 2

Leo can run 8.82 km at the same speed for an hour without running.

Distance covered by Leo (D) = 1 km.

Time taken by Leo to cover it (T) = 34/5 of a minute

= 34/5 minute = 34/(5×60) hours = 34/300 hours   [As 1 minute = 1/60 hour]

So, speed (S) of Leo = D/T

= $\frac{1}{\frac{34}{300} }$ km/hr

= $\frac{300}{34}$  km/hr

So, the distance he can cover in 1 hour = Speed (S) × Time (T)

= (300/34 × 1) km

= 300/34 km

= 8.82 km

Distance covered = 8.82km
