CPM Homework Help : ACC7 Problem 9-12

Ryan and Janelle are each driving from a different location to meet. When they each stopped for lunch at 12 noon, they called each other on their cell phones. Ryan had traveled $245$ miles in $3\frac{1}{2}$ hours. Janelle had driven $260$ miles in $4$ hours.

If Ryan and Janelle were originally $910$ miles apart when they had started driving that morning, at what time will they meet?

Hint:

For each driver, find the speed they traveled by dividing the miles they had driven by the amount of time they had been driving.

More Help 1:

Janelle had been driving at 65 miles per hour, since $260$ miles divided by 4 hours is equal to $65$ miles in each hour. Can you find Ryan's speed?

More Help 2:

Write an equation to find the time ( $x$ ) until they have traveled $910$ miles total. Their rates of travel should be coefficients of $x$ .
