Question

Gwen and Bryn drive to work.

Gwen drives 65 miles in 2.5 hours.
Bryn drives 76 km in 1 hour 15 min.
Work out the difference between their average speeds in km/h

Answer 1

Answer: 18.96 km/h

Explanation:

Gwen:

65 miles = 104.6 km

104.6 km / 2.5 h = 41.84 km/h

Bryn:

15 min = 0.25 h

76 km / 1.25 h = 60.8 km/h

Difference:

60.8 - 41.84 = 18.96 km/h

Hope this helps!
