Question

PLEASE HELP !!! ASAP ! Jill and Scott both road their bikes for 30 minutes. Jill traveled 5 kilometers and Scott traveled 10. Calculate each person's speed and tell who rode faster. (s=d/t)

Answer 1

Answer: Scott rode faster the bicycle faster than Jill

Explanation:

Always Remember that the units should be in the standard form, so first convert minutes into hours

1 hour = 60 mins

Convert mins to hr

So,

60 mins = 1 hour

30 min = 0.5 hours

Jill traveled = 5 Km

Time = 0.5 hours

Speed = distance/time

Speed = 5km/0.5 hr

10km/hr is Jill’s speed

Now find Scott’s speed

Scott traveled =10Km

Time = 0.5 hours

Speed = distance/time

= 10km/0.5hrs

= 20km/hr is Scott’s speed

Answer 2

Ok first of all we have to convert in km/hr=Speed

So 30min are 0.5hours

Then we use S= distance/time = 5km/0.5 hrs = 10km/hr —> Jill speed

Then S= d/t = 10km/0.5hrs = 20km/hr —> Scott speed

So Scott rode faster
