Hi everyone here we have a question telling us a vehicle runs 367 km on a full tank. How many full tanks doesn't need to reach 789 miles. So we're gonna start off with our 789 miles Times 1609 m Divided by one mile, times one kilometer Divided by to the 3rd m, Times one full tank Over 367 km. So our miles are canceling out. Our meters are canceling out. Our kilometers are canceling out and that equals 3.4598 full tanks. And we can't have a decimal point and a full tank of gas. So we need to round up. So we will have we will need four full tanks. And that is our final answer. Thank you for watching. Bye.
