Answer:
8.331 km is the Total Distance Covered.
Step-by-step explanation:
i. Speed = 40 km/hr
= 1 km/hr = 5/18 m/s
= 40 km/hr = 11.11 m/s
Time = 5 mins or, 300 seconds
∴ Distance = Speed = Distance/Time
= 11.11 = Distance/300
= 3333 m = Distance
ii. Speed = 60 km/hr
= 1 km/hr = 5/18 m/s
= 60 km/hr = 16.66 m/s
Time = 5 minutes or, 300 seconds
∴ Distance = Speed = Distance/Time
= 16.66 = Distance/300
= 4998 m = Distance
∴ Total Distance = (3333+4998)m
= 8331 m
or,
= 8.331 km
