Suzette ran and biked for a total of 44.75 mi in 4 h. Her average running speed was 6.5 mph and
riadik2000 [5.3K]

The total hours Suzette biked was 2.5 hours and she ran for 1.5 hours

Let x = total hours Suzette ran.

Let y = total hours Suzette biked

The equation to solve the question will be:

x + y = 4 ....... equation i

6.5x + 14y = 44.75 ........ equation ii

From equation i, x = 4 - y ....... iii

Put the value of x into equation ii

6.5x + 14y = 44.75

6.5(4 - y) + 14y = 44.75

26 - 6.5y + 14y = 44.75

Collect like terms

-6.5y + 14y = 44.75 - 26

7.5y = 18.75

Divide through by 7.5

7.5y/7.5 = 18.75/7.5

y = 2.5

Since x + y = 4

x + 2.5 = 4

x = 4 - 2.5

x = 1.5

Suzette ran for 1.5 hours

In conclusion, the total hours Suzette biked was 2.5 hours and she ran for 1.5 hours.
