Mrs anglin is driving her car at a constant speed of 90 miles in 2 hours select three statements that are true based on her spee
Ira Lisetskai [31]

Answer:

  • She traveled 45 miles in 1 hour
  • She traveled 270 miles in 6 hours
  • She traveled 360 miles in 8 hours

Step-by-step explanation:

If Mrs. Anglin traveled at a speed of 90 miles in 2 hours, it means that her speed per hour is:

= 90/2

= 45 mph

If she is travelling at 45mph then in 1 hoour she would have traveled 45 miles.

In 6 hours she would have traveled:

= 45 * 6

=  270 miles

In 8 hours she would have traveled:

= 45 * 8

= 360 miles
