Aneesha travels at a rate of 50 miles per hour. Morris is traveling 3 feet per second less than Aneesha. Which is the best estimate of the speed Morris is traveling? 1 mile = 5,280 feet
Answers
We know that 1 mile = 5,280 feet.
Given that Aneesha travels at a rate of 50 miles per hour.
= > (50 * 5280)/(60 * 60)
= > 73.3333 feet per second.
Now,
Morris is Travelling 3 feet per second less than Aneesha.
=> Speed of Morris = 73.3333 - 3
= 70.3333 feet per second
= 70.3333 * 0.681818 miles per hour
= 47.9 miles per hour
= ~ 48 miles per hour.
Therefore, Morris is travelling 48 miles per hour.
Hope this helps!
3 feet/second
= 3 feet/second x 60 seconds/minute x 60 minutes/hour
3 x (60 x 60) = 3 x 3600 which is slightly more than that 10,000
So 3 feet/second is slightly more than 10,000 feet/hour
we know that there are 5,280 feet in a mile
we will round this figure to 5,000 feet per mile
The estimated speed difference is
10,000 feet/hour /5,000 feet/mile
this will be equal to 2 miles/hour
With this we can make an estimate that Morris is travelling with around 2 miles/hour and Aneesha is given 60 miles/hour or maybe around 58 miles/hour
So difference between 60 miles/hour vs 58 miles/hour will give a value of around 2.933 feet per second which is approximately closer to 3 feet per second.
