Mark my answer as the brainliest please...
Explanation:
a) d = 30 km
t = 30 minutes
S = d/t
= 30 km/30 min
= 1 km/min :----- Answer
b) 1 minute = 30 seconds
30 minutes = 30 × 30 seconds
= 900 seconds
1 km = 1000 m
30 km = 30 × 1000 m
= 30000 m
Speed(in m/s) = 30000 m/900 secs
= (100/3) m/s :----- Answer
