Question

Ramesh rides his bike for 5/4 km to reach his school .He can ride 3/8 km in one minute .How long will it take him to reach the school?​

Answer 1

Answer:

He takes, approximately, 3.333 minutes to reach school.

Step-by-step explanation:

His distance to school is $\frac{5}{4}$ km.

We know that it takes him 1 minute to ride $\frac{3}{8}$ km.

The distance left after 1 minute is equal to:

$\frac{5}{4} - \frac{3}{8}$ = $\frac{7}{8}$ km.

Then, after 1 minute he has $\frac{7}{8}$ km left to ride.

Hence we can do a simple rule:

1 minute  -----  $\frac{3}{8}$

x minutes  -----  $\frac{7}{8}$

x = $\frac{\frac{7}{8} }{\frac{3}{8} }$

x = $\frac{7}{3}$

Thus, he takes 1 + $\frac{7}{3}$ minutes to reach the school.

1 + $\frac{7}{3}$ = $\frac{10}{3}$

Hence the answer is, approximately, 3.333 minutes.
