Answer:
1.5m/s
Explanation:
Using the formula;
Speed (m/s) = distance (metres) ÷ time (seconds)
According to the information provided in this question, Heather and Matthew spend 60seconds to travel a distance of 90 metres. This means that t = 60s, d = 90m
Hence,
Speed = 90/60
Speed = 3/2
Speed = 1.5m/s.
