Draw a distance-time graph

to show Don's journey.

Please find the attached traced distance time graph

Step-by-step explanation:

The given parameters are;

The time at the start of Don's journey = 2 pm.

The distance Don drives one hour after leaving home = 45 miles

The speed (Distance/time) Don drove during that time = 45/1 = 45 mph

The time at which Don first stop driving = 2 pm + 1 hour = 3 pm

Don then stops for 90 minutes

The time after the duration at which Don stops driving = 3 pm + 90 minutes = 3 pm + 1.5 hours = 4.30 pm

At 4.30 pm. Don then starts driving home at 15 mph

The distance from Don's home from where Don stopped is 45 miles, therefore;

Time (Distance/speed) for Don to get home = 45 miles/15 mph = 3 hours

Time Don arrived home = 4.30 pm + 3 hour = 7.30 pm.
