Answer 2

Question

John is riding his bike at a constant speed of 30 km /h. If he started his journey at 6 am, calculate when he will reach his destination that is 90 km away.

Given :

speed of John's bike = 30 km/h

starting time = 6 am

To Find :

Time at which he will reach his destination

Formula to be used :

$\large\sf\frac{distance \: covered}{time \: taken}$

Solution :

Let the time taken for Jhon 's journey be ' to'

30km/h = $\large \sf\frac{90 \: km}{t}$

∴ t = $\large\sf\frac{90 \: km}{30km}$

∴ It takes Jhon 3h to complete his journey, so he will reach his destination that is 90 km away, at 9 am
