Ian drives an electric car. He can drive 425 kilometres before he needs to stop and recharge his car. It takes 10 minutes to charge 50 kilometres. How long does Ian have to wait for his car to fully charge?

85 minutes

Step-by-step explanation:

425/50=8.5 10 minute increments

8.5*10= 85 minutes

85 minutes

Step-by-step explanation:

Of it takes 10 minutes to recharget 50 kilometres and we need to find for 425 kilometres, therefore

10 minutes = 50 kilometres

x minutes = 425 kilometres

Cross multiply

50 × x = 425 × 10

50x = 4250

Divide both sides by 50

x = 4250 ÷ 50

x = 85 minutes

i really dont know

step-by-step explanation:

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
