Answer:
1.25 hours
Step-by-step explanation:
Benjamin rode tghe train for 45 minutes. Then it took him another 30 minutes to walk to his friend's house. How many hours did he spend riding and walking to his friend's house?
The number of hours he spent riding and walking to his friends house is calculated as:
45 minutes + 30 minutes
= 75 minutes
Converting this to hours
60 minutes = 1 hour
75 minutes = x
Cross Multiply
60 × x = 75 × 1
x = 75/60
x = 1.25 hours
The equation should be y=-2x .
