Warren · Answer 1

v = 80 km/hr

Explanation:

Given that

Time t = 1 minute 48 seconds

We know that

1 min = 60 sec

1 sec = 1/60 min

1 hr = 60 min

1 min = 1/60 hr

t = 1/60 + 48/3600 hr

t = 0.03 hr

Given that distance d = 2400 m

d = 2.4 km

We know thart

d = v. t

v = speed

2.4 = v x 0.03

v = 80 km/hr
