speed 1 = 36 km/ hr , time1 = 15 minutes
t1 = 15 ÷ 60 = 1/ 4 hrs
distance1 = s1 × t1= 36 ×( 1/ 4)
= 9 km
speed2 = 60 km/ hr , time2= 15min
= 1/ 4 hr
distance2 = s2 × t2
= 60 × ( 1/ 4) = 15 km
Answer:
-------------
total distance covered = 9 + 15 = 24 km
t1 = 15 ÷ 60 = 1/ 4 hrs
distance1 = s1 × t1= 36 ×( 1/ 4)
= 9 km
speed2 = 60 km/ hr , time2= 15min
= 1/ 4 hr
distance2 = s2 × t2
= 60 × ( 1/ 4) = 15 km
Answer:
-------------
total distance covered = 9 + 15 = 24 km

1. speed = 36 km/hr
time= 15 minutes
time = 15/60 = 1/4 hr
distance = 36×1/4 = 9 km.
2. speed = 60 km/ hr
time = 15 minutes
time= 15/60 = 1/4hr
distance= 60× 15 = 15 km
total distance = 9+15 = 24 km
