Question

Jake completed a marathon race in 3 hours and 12 minutes. What would be Jake's running time as a decimal?

Answer 1

`\text{Given that Jake completed a marathon race in 3 hours and 12 minutes.}\\ \\ \text{we need to find this time in decimals. so we will convert 12 minutes into hours}\\ \\ \text{We know that there are 60 minutes in 1 hour. }\\ \\ \text{so in 1 minute there will be}=(1)/(60 )\text{ hour}`

`\text{hence in 12 minutes we have}=(1)/(60)* 12=(1)/(5)=0.2 \text{ hours}\\ \\ \text{hence the Jake's running time is}=3\text{hours + 12 minute}\\ \\ =3\text{ hours}+0.2 \text{ hours}\\ \\ =3.2 \text{ hours}`

Hence, Jake's running time in decimal is: 3.2 hours
