First case
speed = 20 km/hr
time = 15 min
1 min = 1 / 60 hr
15 min = 15 / 60 hr
= 1 / 4 hr
speed = distance / time
==> distance = speed × time .
==> 20 km/hr × 1/4 hr
==> 5 km
Second case
speed = 60 km/hr
time = 15 min
= 1/4 hr
distance = speed × time
= 60 km/hr × 1/4 hr
= 15 km
Total distance
Total distance = 15 km + 5 km
= 20 km
The total distance covered is 20 km
