3 A car travels 30 km each hour.
About how many hours would it take
to go each distance?
a) 3200 km
b) 1700 km
c) 5720 km



Answer :

Sure! Let's calculate how many hours it would take for a car traveling at 30 km per hour to cover each of the given distances step-by-step.

### Part (a): 3200 km
To calculate the time taken, we use the formula:
[tex]\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \][/tex]

For a distance of 3200 km:
[tex]\[ \text{Time} = \frac{3200 \text{ km}}{30 \text{ km/hr}} \][/tex]
[tex]\[ \text{Time} = 106.67 \text{ hours} \][/tex]

Thus, it would take about 106.67 hours to travel 3200 km.

### Part (b): 1700 km
Using the same formula, let's calculate the time:
[tex]\[ \text{Time} = \frac{1700 \text{ km}}{30 \text{ km/hr}} \][/tex]
[tex]\[ \text{Time} = 56.67 \text{ hours} \][/tex]

Therefore, it would take about 56.67 hours to travel 1700 km.

### Part (c): 5720 km
Again, we use the same formula:
[tex]\[ \text{Time} = \frac{5720 \text{ km}}{30 \text{ km/hr}} \][/tex]
[tex]\[ \text{Time} = 190.67 \text{ hours} \][/tex]

So, it would take approximately 190.67 hours to travel 5720 km.

To summarize:
- It takes about 106.67 hours to travel 3200 km.
- It takes about 56.67 hours to travel 1700 km.
- It takes about 190.67 hours to travel 5720 km.
