Question

2hours at 30km/h 7 hours at 65 km/h 1/2 hours at 46 km/h 45 minutes at 80 km/h 1 1/2 hours at 55km/h fors numbers 1-5, calculate the distance that you would travel if you drove for;

Answer 1

Answer:

60 km

455 km

23 km

60 km

82.5 km

Step-by-step explanation:

Time = t

Speed = s

Distance is given by

$d=s\times t$

t = 2 hours

s = 30 km/h

$d=30\times 2=60\ \text{km}$

Distance driven is 60 km.

t = 7 hours

s = 65 km/h

$d=65\times 7=455\ \text{km}$

Distance driven is 455 km

t = $\dfrac{1}{2}\ \text{hours}=0.5\ \text{hours}$

s = 46 km/h

$d=46\times 0.5=23\ \text{km}$

Distance driven is 23 km

t = 45 minutes = $\dfrac{45}{60}=0.75\ \text{hours}$

s = 80 km/h

$d=80\times 0.75=60\ \text{km}$

Distance driven is 60 km

t = $1\dfrac{1}{2}\ \text{hours}=1.5\ \text{hours}$

s = 55 km/h

$d=55\times 1.5=82.5\ \text{km}$

The distance driven is 82.5 km
