Koshanah rode her bike for 35 minutes on monday, wendsday, and saterday and 55 minutes each on tusday and thersday . Write an ex

dem82 [27]

Answer:

215 minutes

Step-by-step explanation:

Let

Number of days she rode for 35 minutes = x

Number of days she rode for 55 minutes = y

Total time spent riding her bike = 35x + 55y

x = Monday + Wednesday + Saturday

x = 3 days

y = Tuesday + Thursday

= 2 days

Substitute into the equation

Total time spent riding her bike = 35x + 55y

= 35(3) + 55(2)

= 105 + 110

= 215 minutes
