PLEASE HELP ME
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.
1 mile = 1.6 km

Answer 1

Answer:

-19.2

Step-by-step explanation:

distancebytime=speed

gwen:104km(65miles)/2.5hrs=41.6km/hr(average speed)

bryn:76kms/1.25hrs=60.8km/hr(average speed)

difference of their average speed :

41.6-60.8=-19.2
